14+ 1 Km Fm Transmitter Circuit Diagram. With a matching antenna, the fm transmitter circuit shown here can transmit signals up to 2 kilometers. Here is circuit diagram of simple fm transmitter.
This fm transmitter has 3 rf stages. Carrier signal (with carrier frequency). This small power fm transmitter can transmit more than 1 km in good conditions.
If you have difficulty adjusting, remove the coil and wind it up again with more or less turns.
